Description

Technical Field

[0001] The utility model belongs to the technical field of rubber rollers, in particular to an EPDM rubber roller for light-color printing and dyeing. Background Art

[0002] For heatable printing and dyeing rubber rollers, there are two types: direct heating and indirect heating. Direct heating means using heating equipment to directly release heat to the roller surface, while indirect heating means transferring the temperature to the roller surface through media such as water or gas.

[0003] However, since the rubber roller is mainly composed of a roller surface, two side plates, a core shaft and a rubber layer sleeved on the outside of the roller surface, the existing heating device and method will not be able to quickly transfer the temperature to the rubber layer, thereby affecting the temperature conduction, and the temperature control effect and timeliness are not good. At the same time, the problem of uneven temperature will occur. For example, when the temperature is conducted by using a medium, the heat is absorbed during the transfer process, so the roller surface temperature close to one end of the medium inlet will be higher than the roller surface temperature at the other end. If it is applied to printing and dyeing rubber rollers, it will greatly affect the printing and dyeing quality and efficiency.

[0004] Therefore, designing a printing and dyeing rubber roller that can be heated quickly and evenly is a problem that needs to be solved by those skilled in the art. Utility Model Content
